Battery discharge protection
Vehicle battery state of charge
function
The function guarantees longest
vehicle battery life via a generator
with controllable power output and
optimised power distribution.
To prevent discharge of the vehicle
battery when driving, the following
systems are reduced automatically in two stages and finally switched off:
● auxiliary heater
● heated rear and front window
● heated steering wheel
● heated mirrors
● heated seats
● fan
In the second stage, a message
which confirms the activation of the
vehicle battery discharge protection
will be displayed in the Driver

Driving and operating229Caution
Performance of the system can bereduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Notice
It is possible that the sensor detects a non-existing object caused by
echo disturbance from external
acoustic noise or mechanical
misalignments (sporadic false
warnings may occur).
Make sure that the front number
plate is properly mounted (not bent
and no gaps to the bumper on the left
or right side) and the sensors are
firmly in place.
Advanced parking assist system
may not respond to changes in the
available parking space after
initiating a parking manoeuvre. The
system may recognize an entry, a
gateway, a courtyard or even a crossing as a parking slot. After
selecting reverse gear the system
will start a parking manoeuvre. Take care regarding the availability of the
suggested parking slot.
Low curbs and surface irregularities,
e.g. on construction zones, are not
detected by the system. The driver
accepts responsibility.
Notice
New vehicles require a calibration
during first use. For optimal parking
guidance, a driving distance of at
least 6 miles, including a number of
bends, is required.System is calibrated to factory-fitted
wheels. Parking performance is
altered with other tyre or wheels
sizes.
Side blind spot alert
The Side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system
displays a visual alert in each exterior mirror, when detecting objects that
may not be visible in the interior and
exterior mirrors.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
● vehicles outside the side blind zones which may be rapidly
approaching
● pedestrians, cyclists or animals
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
230Driving and operating
When the vehicle is started, both
exterior mirror displays will briefly illuminate to indicate that the system
is operating.
When the system detects a moving
vehicle in the side blind spot while
driving forwards, either while passing a vehicle or being passed, a yellow
warning symbol F will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol F starts
flashing yellow as a warning not to
change lanes.
Side blind spot alert is active at any
speed.
Deactivation
Activation or deactivation of the Side
blind zone alert can be set in the
vehicle personalisation menu in the
Info-Display.
Vehicle personalisation 3 123.
Info-Display 3 117.
Deactivation is indicated by a
message in the Driver Information
Centre.
System limitations Occasional missed alerts can occur
under normal circumstances or in
sharp curves. The system can
temporarily alert of objects in the blind spot at specific weather conditions
(rain, hail etc). Driving on a wet road
or in the transitions from a dry area to a wet area can cause the control
indicator F to light up, as water
splash can be interpreted as an object. Otherwise the control indicator
F may illuminate due to guardrails,
signs, trees, shrubs or other immobile
objects. This is normal operation and
the system does not need to be
serviced.The system may not operate properly
when:
● Ice, snow, mud, stickers, magnets, metal plates, or
anything else covers the sensors.
● Driving in heavy rainstorms.
● The vehicle had an accident or if the area surrounding the
detection sensor is damaged or
not properly repaired.
● There are extreme temperature changes.
● The vehicle is towing a trailer
In the event of a fault in the system or if the system does not work due to
temporary conditions, a message is
displayed in the Driver Information
Centre. Seek the assistance of a
workshop.
Notice
After production, the system
requires a calibration. For optimal
performance, drive as soon as
possible on a straight highway road
with roadside objects, e.g. guardrails
and barriers for some distance.
Driving and operating231Lane change alertAdditional to the side blind spot alert
3 229, lane change alert recognizes
rapidly approaching vehicles from
behind on parallel lanes next to your
vehicle.
The system alerts visually in each
exterior mirror when detecting rapidly
approaching vehicles from behind.
The radar distance sensors are
located in the rear bumper.9 Warning
Lane change alert does not
replace driver vision.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects an
approaching vehicle from behind
which drives considerably faster, the
yellow warning symbol F will
illuminate in the relevant exterior mirror. If the driver then activates the
turn signal, the warning symbol F
starts flashing yellow as a warning not to change lanes.
Lane change alert is active at all
speeds.
When the vehicle is started, both
exterior mirror displays will briefly come on to indicate that the system is operating.
Detection zones
The system sensors cover a zone of
approx. 3.5 metres parallel on both
vehicle sides and approx. 3 metres
rearwards on side blind zone alert
(A) and approx. 50 metres rearwards
on lane change alert (B) on parallel
lanes. The zones start at each
exterior mirror. The height of the zone
is approx. between 0.5 metres and
2 metres off the ground.
Deactivation
Activation or deactivation of the lane
change alert can be set in the vehicle personalisation menu in the Info-
Display.
